As the middle-aged witch Blanchett performed spellcasting movements that Shard couldn't understand, the slender branches of the newly grown sapling continued to grow. Not only did the branches extend, but the sprouting green leaves also transformed into tiny green figures after falling, quickly filling the branches of the small tree.
They sat snugly on the branches, each holding a different instrument.
As the witch paid her respects to the Deity and then rose to prepare to sing, the "miniature" orchestra on the little tree began playing as well.
It seems that singing is an essential skill for witches, for as soon as Mrs. Blanchett began, Shard realized that Mr. Lyman and Sister Perry had no chance of winning.
